Some players like them more than others.
I personally don't tend to use them much, but I will depending on the music and the style. Some bass lines call for it. Some were designed for it.
If I'm playing a four-string, or if I'm playing a bass and prioritizing the EADG strings for a specific style of music or a specific song, then I will use open strings on occasion. These styles of music generally tend to be in keys that have sharps and are common to guitars. (And, of course, there's only one E1 on the fretboard, and it's the open position.)
If I'm playing on something other than a four-string, and I'm not playing in common guitar keys - basically, most keys with flats - then I will usually not use open strings, even if the opportunity exists.
Open strings can be useful for easily playing contrapuntal lines and executing melodies that have large ranges or pedal tones. Unfortunately, due to the nature of the bass guitar, it really only works in certain keys with certain tonal centers and only in certain situations, so I find that it's not really all that useful. Furthermore, I personally find that the register is also important, so playing pedal tones would be more likely to happen on the E and A strings than the G string. This presents even more limitations. Two-handed playing/tapping would be a better way to execute melodies and lines like this in any key without being tied to open strings.
They aren't inherently good or bad, but - especially on a four-string bass - I think the cases where they can be used in a creative way are far fewer than the cases where they can't be. Even on my six-string, I find that attempting to use open strings in a creative way limits me to the same old keys.
